VoIP Phone and VoIP ATA

VoIP phone is a telephone set designed specifically for use in a voice over IP (VoIP) system by converting standard telephone audio into a digital format that can be transmitted over the Internet, and by converting incoming digital phone signals from the Internet to standard telephone audio. A VoIP phone allows the user to take advantage of VoIP technology without involving a personal computer, although an Internet connection is required.

Physically, a VoIP phone set resembles a traditional hard wired or cordless telephone set. It employs the familiar ear and mouth (E&M) arrangement with an earphone (or earpiece) for listening to incoming audio, and a microphone (or mouthpiece) for transmitting audio. Some VoIP phone sets offer enhanced quality audio, comparable to that on compact disc(CD). A few VoIP phone sets allow for the transmission and reception of image data during calls, so they can be considered video telephones

An analog telephone adaptor (ATA) is a device used to connect a standard telephone to a computer or network so that the user can make calls over the Internet. Internet-based long distance calls can be substantially cheaper than calls transmitted over the traditional telephone system, and ATAs are typically cheaper than specialized VoIP phones that connect directly to a computer’s Universal Serial Bus
